求項１記載の内径測定器。[Claims for Utility Model Registration] 1. An air micrometer-type inner diameter measuring device having a measuring tip inserted into a hole to be measured whose inner diameter is to be measured and having an outer diameter slightly smaller than the hole to be measured, Air supply means that forms a tapered part at the tip of the probe and supplies air from the side opposite to the probe insertion side to the probe hole when the probe is attached to and removed from the probe hole. An inner diameter measuring device characterized by being provided with. 2. Provided with a moving mechanism for inserting or pulling out the measuring element into the hole to be measured,
This moving mechanism moves the gauge head through a flexible support that allows angular displacement of the center axis of the gauge head and positional displacement in two perpendicular directions within a plane orthogonal to the center line of the hole to be measured. The inner diameter measuring device according to claim 1, characterized in that it is supported.
